Which type of pump is more appropriate for liquid ammonia pumps?
Thread Content
Our company needs a liquid ammonia pump with a flow rate of only 0.7 m3/h, and it must be completely leak-free； For magnetic pumps and shielded pumps, the flow rate is too low. Can the vane pump meet the requirements? Are there any other pumps available? Can the YAB-type liquid ammonia pump meet the requirements?
How much head do you need? Our company has a model with low flow rate but high head, which should meet your requirements

It is recommended to use a full PTFE diaphragm pump with a leak alarm
Domestic sliding vane pumps are also good; you might give them a try
The sliding vane pumps manufactured by our company can transport liquid ammonia, and they can also be designed as magnetically driven sliding vane pumps. Zero leakage. You can add me on WeChat
It’s a diaphragm metering pump; the diaphragm is made of polytetrafluoroethylene, and it’s hydraulically driven. We use it here to transport monomethylamine, and it works very well.
A double-shell magnetic pump is used, with a flow rate range of 0.1–1000 cubic meters. It features a dual-layer isolation sleeve system: if one layer fails, the second layer continues to provide protection, triggering an alarm as a safety measure. It can be installed on the ground with a NPSH of 0.5, and it allows the presence of a certain amount of solid particles. Technical exchanges are available if needed
It depends on whether you will use it at low temperatures or at normal temperatures – shielded pumps are designed for low temperatures and have a relatively low flow rate. For normal temperature applications, Japanese reverse-circulation pumps can be used; however, the head requirement cannot be too high (anything over 100 is considered high)
